### 1/5 — Ripoff! DO NOT BUY!

*2025-09-17*

This is a ripoff of Wikipedia and most of the links do not work! Seriously, $9.00 to read Wikipedia?! I bought it to review the app, but it sucked so bad, I had to request a refund!

### 5/5 — I think therefore I download

*2020-10-09, version 1.0.4*

Concise and easy to use. This app covers the foundational ideas in philosophy and their histories. It also goes into some of the more advanced theories. I would completely recommend for those who are new to philosophy and more advanced students who want to brush up and revise alike! A great find.

### 1/5 — Plagiarised shamelessly from Wikipedia

*2020-07-31, version 1.0.4*

As the title says....
and they want to charge me £9.99 to 'unlock' more of Wikipedia?

Er, no thanks.

### 5/5 — 😀😀😀

*2018-07-30, version 1.0.4*

“Tidy”

### 5/5 — Really interesting and well organised compilation of the western history of philosophy

*2018-03-14, version 1.0.4*

Really useful and interesting. Especially for students

### 1/5 — Lightweight

*2017-12-08*

I was very disappointed when I searched for information on a few philosophers I am interested in.  Derrida,Lacan,Machiavelli, Schopenhauer, Hume, Jung, Rand & Wittgenstein were not found.

### 1/5 — Answers?

*2016-09-27*

There appears to be substantial information that due to the ineffective software implementation is totally inaccessible.☹️️

### 2/5 — Why should I pay you for Wikipedia?

*2016-08-28*

This app admittedly takes Wikipedia commons articles and then charges us to read them. Seems a bit shady and opportunistic. I was expecting something more than just copy and paste Wiki articles, that aren't even attributed correctly. They removed the footnotes out of many of them so you don't know the original sources of the materials making it useless for research purposes. Just Google the topic or download Wikipedia and if you want to pay someone, pay Wikipedia since they are the REAL authors and collaborators of the material.
